Everything in the HighLite`s design is intended to reduce weight and promote compressibility. First the .9 ounce ExtremeLite shell fabric goes without saying. No other shell fabric is this light or packed with so many threads per inch.
This specialized ExtremeLite bag uses a one way #4 1/2 YKK coil zipper that is cut to half length.
While the horizontal seams are sewn-thru the vertical seams are baffled with 1 1/2` netting to allow unimpeded loft so the effect of its 850+ goose down is fully realized. Its efficient cut not only reduces bulk and weight but reduces excess internal volume so quick heating is realized! At only 455g total weight no other bag is as light as warm as well made or as handsome as our HighLite.

Western Mountaineering down gear has an awesome reputation in the US and that reputation is beginning to build on this side of the pond. Very high quality materials design and construction results in the lightest bags available for a given warmth.
An example of their attention to detail is their quoted 850+ fill power down used in all their bags: WM quote this figure even though their down generally gets higher ratings in official tests this is because they feel that the official pre-testing preparation enhances the down quality!

* Western Mountaineering state: 'We independently verify own temperature ratings through our own testing, customer feedback and design knowledge. Most of the items in our catalog we have been making for years, which means we have lots of prior knowledge from everyday consumers on what ratings are accurate. We have also EN tested our bags. In every case the EN rating is lower than our posted rating. This means our ratings are more conservative. We do this to ensure that almost everyone will be happy in our bags at the temperature we publish.'
